Project description
This is a PCB for my automated garden watering project with IoT. The goal is to have your plants environment perfectly controlled using individual sensors for every batch of plants or pots and water them according to an individual threshold. All is controlled from a central PCB with an Arduino Mega and an ESP8266 to be able to connect to the system through Blynk cloud / app on your phone. What i have used to realize this project: - Arduino Mega - ESP8266 https://www.aliexpress.com/item/Free-shipping-50pcs-lot-ESP8266-serial-WIFI-wireless-module-wireless-transceiver/32256873477.html?spm=a2g0s.9042311.0.0.53724c4dnlPGNc - Water Pump (In order to get sufficient pressure on the water you need a pump with <20W) https://www.aliexpress.com/item/Durable-DC-12V-70-PSI-Agricultural-Electric-Water-Pump-Mayitr-Black-Micro-High-Pressure-Diaphragm-Water/32820165719.html?spm=a2g0s.9042311.0.0.27424c4dT8VtH9 - Valves https://www.aliexpress.com/item/G1-4-Solenoid-Valve-Plastic-Normally-Closed-2-Way-12V-DC-0-120PSI-0-0-8MPa/32829245020.html?spm=a2g0s.9042311.0.0.53724c4dnlPGNc - Capacitive moisture sensot https://www.aliexpress.com/item/10pcs-Capacitive-soil-moisture-sensor-not-easy-to-corrode-wide-voltage-wire-for-arduino/32859931034.html?spm=a2g0s.13010208.99999999.259.30453c00bblSaK - This PCB and all related components (+ some SMD soldering skills) - Programming skills for Arduino Mega - Flashing of ESP8266
